pls help me to build water level meter.the one i made uses 5 probes for empty,quarter,half and full.Now a want a better design.can i use uvison and simulate something. what
One simple design is to use a potentiometer and an arm with a flotation device. That will give you a continuous measurement.
You can also build a capacitive sensor that measures hwo much water you have in a pipe. Or you could use an ultrasound microphone and measure the time of the sound returning after being reflected by the water surface. You could also use a web camera and perform image analysis of how high the water reaches on a wall or stick. There are a number of other options possible too.
There are many alternatives possible. Use your imagination, and then sit down and figure out the mechanical, electrical and programmatic consequences of the different solutions.
Not before you've done some thinking about what you actually want to simulate!
What are your requirements for this meter?
In what way(s) must it be "better" than your existing meter?
In other words, what is "wrong" with the existing design?
start by keeping your pc and uVision far away from the water...
